DESCRIPTION="Based on the ${ECLASS} eclass"

# This function generate linker scripts in /usr/lib for dynamic
# libs in /lib.  This is to fix linking problems when you have
# the .so in /lib, and the .a in /usr/lib.  What happens is that
# in some cases when linking dynamic, the .a in /usr/lib is used
# instead of the .so in /lib due to gcc/libtool tweaking ld's
# library search path.  This cause many builds to fail.
# See bug #4411 for more info.
#
# To use, simply call:
#
#   gen_usr_ldscript libfoo.so
#
# Note that you should in general use the unversioned name of
# the library, as ldconfig should usually update it correctly
# to point to the latest version of the library present.
#

/* GNU ld script
   Because Gentoo have critical dynamic libraries

   need to have a "fake" dynamic lib in /usr/lib,
   otherwise we run into linking problems.

# This function is for bulk patching, or in theory for just one
# or two patches.
#
# It should work with .bz2, .gz, .zip and plain text patches.
# Currently all patches should be the same format.
#
# You do not have to specify '-p' option to patch, as it will
# try with -p0 to -p5 until it succeed, or fail at -p5.
#
# Above EPATCH_* variables can be used to control various defaults,
# bug they should be left as is to ensure an ebuild can rely on
# them for.
#
# Patches are applied in current directory.
#
# Bulk Patches should preferibly have the form of:
#
#   ??_${ARCH}_foo.${EPATCH_SUFFIX}
#
# For example:
#
#   01_all_misc-fix.patch.bz2
#   02_sparc_another-fix.patch.bz2
#
# This ensures that there are a set order, and you can have ARCH
# specific patches.
#
# If you however give an argument to epatch(), it will treat it as a
# single patch that need to be applied if its a file.  If on the other
# hand its a directory, it will set EPATCH_SOURCE to this.
